Abstract
Two unrelated patients had dry brittle hair, alopecia, trichorrhexis nodosa, dry scaly skin, pigment dyschromia, short stature, and neurosecretory growth hormone deficiency. By means of the zinc tolerance test, patient 1 was shown to have zinc deficiency, whereas no clear zinc deficiency could be demonstrated in patient 2. In both patients, hair and the skin abnormalities responded to oral zinc therapy.
